Which of the following is a sign that pests may be present?

• A. Live or dead bodies
• B. Dry storage
• C. Good lighting
• D. Temperature control

Answer: (A)

The key idea here is recognizing direct indicators of pest activity. Finding live or dead pests provides concrete evidence that pests are or have been in the area, which immediately signals a pest issue that needs action under HACCP pest control procedures. The other options describe conditions or controls rather than evidence of pests: dry storage is about reducing harborage and access but doesn’t itself show pests; good lighting helps visibility and safety but doesn’t indicate whether pests are present; temperature control helps prevent pest growth but is a preventive measure, not proof of presence. In practice, you’d also look for other signs like droppings, gnawed packaging, or unusual odors, but live or dead bodies are the clearest sign that pests may be present.
